You could own Tom Seaver's 1969 World Series cap

The matchups haven’t all been set yet, but we’re about to begin another season of playoff baseball. And for the first time in 9 years, I have a real rooting interest.

But while we’re waiting, let’s take a look at a piece of memorabilia from the Mets’ first World Series appearance.

If you’ve got $9,999.99 burning a hole in your pocket, you could own the cap Tom Seaver wore in 1969. Press Pass Collectibles is selling the cap, which had previously been owned by a family member of a former Shea Stadium security officer.
